ENVELOP.

SPECIFICATION forming part of Letters Patent No. 707,074, dated August 19, 1902.

Application filed July 22, 1901. Serial No. 69,250. (No model.)

To all whom, it may concern:

Be it known that I, LYDIA A. BENNETT, a citizen of the United States, residing at Cleveland, in the county of Ouyahoga and State of Ohio, have invented a certain new and useful Improvement in Envelops; and I hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it pertains to make and use the same.

My invention relates to envelops which may be used to transmit either first-class or second class mail-matter.

My invention consists in the peculiar formation of the envelop whereby the sealing of the same is doubly secure and whereby it is impossible to obtain access to the inclosure of the envelop without mutilating the envelop in such a manner that an attempt to obtain access to the interior may be quickly and positively determined.

In the drawings, Figure I is a plan view of an envelop-blank constructed according to my invention. Fig. II illustrates an envelop constructed accordingto my invention, showing the same closed and before the lockingslit has been secured in position. Fig. III illustrates an envelop on the reverse side to that shown in Fig. II and showing the same after the securing-slit has been inserted in position and after the envelop has been addressed and passed through the hands of the post-office canceling-clerk. Fig. IV is a detail view of a corner of the address side of an envelop, illustrating the manner of securing the locking-slit in position and before the stamp is placed in position on the envelop.

A represents a blank formed with the usual side and bottom slats a, a, and c and the upper or top flap I5. In forming the upper or top flap B, I form integral therewith a projecting slip b, which is located at the upper portion of said flap when the same is in closed position, as illustrated in Fig. II of the drawings. The inclined edge of the flap 1), on which the projecting slip or tongue Z) is formed, terminates at a point adjacent the upper end of the body of the blank A in a horizontal edge, which edge extends ontwardly to the edge of the body of the blank and merges into thetapering slip I). From the foregoing description will be perceived that I form the slip I) at one side of the envelop only.

0 represents a slot which is formed in the address face or side of the envelop and located in such a position that when the envelop is closed, as illustrated in Figs. II and III, the end of the slip b may be inserted in the slot O, as illustrated in Fig. IV. The slip b is provided with adhering gum on its exterior face, as illustrated by dotted lines in Fig. IV, and hence whenthe slip Z) is inserted within the slot 0 after having been previously moistened it will adhere to the inner face of the addressed side of the envelop and cannot be loosened therefrom without being mutilated. In order toafford further security, the slip b and slot O are located in such a position at the right-hand upper corner that when the stamp is properly placed it will cover the slot 0 and a portion of the slip Z), and hence be in such position that when the canceling-stamp is used, as illustrated in Fig. III, for the purpose of canceling the stamp D the canceling-lines will run onto the slip b and any attempt to interfere with the slip for the purpose of opening the envelop may be easily detected.

As heretofore mentioned, but one side of the envelop is provided upon the upper flap with the slip b and corresponding slot O in the body, which may be used Without sealing for the purpose of transmitting secondclass mail-rnatter, thus holding the upper flap on place and permitting the examination by postal authorities of the contents.

It will be clearly seen that as far as econ omy of construction is concerned there is no extra Waste in the material in cutting out the blank, as illustrated in Fig. I, and in the manufacture of the envelop the gum may be applied just as quickly and with one handling to the inner face of the envelop-flaps and with the outer face of the slips by bending down said slip b, as illustrated by dotted lines in Fig. I. Also the slip b may be bent to the position illustrated in Fig. I and left there for the purpose of economy in packing.

What I claim is--'- In an envelop of the type set forth the combination with the body thereof, of a closing flap formed with inclined edges, one of said inclined edges terminating adjacent the upend received in the slot, and sealed to the interior of the envelop, said exposed portion of the slip adapted to be covered by the stamp, for the purpose specified. 15

Signed by me at Cleveland, county of Guyahoga, and State of Ohio, this 18th day of July,
